RHEV-M reports ceases to work after some time
Issue
The reports portal was found to be unavailable.
Both the data warehouse service and the jasperserver logs had references to database connections exhaustion, e.g:
ovirt-engine-dwhd.log:2014-02-06 19:00:24|PanvZ8|NaG6rr|EOxIEr|OVIRT_ENGINE_DWH|SampleTimeKeepingJob|Default|6|Java Exception|tJDBCConnection_1|org.postgresql.util.PSQLException:FATAL: sorry, too many clients already|1
server.log:2014-02-06 17:32:19,283 INFO [stdout] (ServerService Thread Pool -- 37) Caused by: org.postgresql.util.PSQLException: FATAL: sorry, too many clients already
A restart of the data warehouse service allowed it to continue, but the reports portal was still inaccessible.
